Foggy Week for the Falls

Foggy Week for the Falls

After seven straight days, Thursday was the first morning Texoma was not under a dense fog advisory. And while fog isn't rare in the Red River Valley, dense fog for this long of a stretch is.

"On average we get about 10-15 days of dense fog a year, so your talking about 25-30 percent of your dense fog days in the last week," Meteorologist for the National Weather Service in Norman Marc Austin said.

The reason for the prolonged period of fog has to do with our stagnant weather pattern.

"We really haven't seen a good front in a while, and a front kind of acts like a broom to sweep out the low level moisture," said Austin.

Over the past week, southern Oklahoma and north Texas have seen some breathtaking fog. In Dallas, the tops of skyscrapers were barely visible. And on Monday night in Wichita Falls, visibility at Sheppard Air Force Base went from 7 miles to a quarter of a mile in one hour.

"We probably had southerly low level flow which is bringing in more and more moisture," Austin explained, "and even though we probably had some clouds, as soon as the temperature dropped and got to that critical threshold, the dewpoint, that's when our humidities rise through the roof and why we saw that fog develop so rapidly."

Austin says whenever fog hits, if you need to be on the roads, make sure to give yourself plenty of extra time to get to your final destination.

"The last thing you want to do is start going really fast and speeding out there, when you don't necessarily know what's in front of you," Austin cautioned.

The challenge for the next two days is predicting whether low clouds will inhibit fog development. By Sunday, when a cold front comes through, we should start to see less foggy conditions.
